UNIQUE LOW NOISE GERMANIUM AND SILICON EVOLUTION OF MY 1961 DESIGN |
History
The Concorde+ Treble
Booster is housed in our standard sized enclosure design and
uses both silicon and germanium transistors in a unique
configuration to obtain the best tone qualities from the marriage.
When I first started designing pedals in 1961 I produced a Treble
Booster that was tried and used by my friends including Jimmy Page
who then played in local bands. DRIVE:
The operational window has been carefully adjusted to set
the gain of the silicon 1st stage to drive the treble booster
section with clean signal levels that are higher than those
obtained from the guitars pickups. When the drive is increased
from it's minimum setting the 1st stage will begin to distort and
you now are in the new territory of having smooth distortion
followed by EQ and then the treble booster section. This area of
operation is very useful as the germanium output stage is driven
harder. So it is possible to set the DRIVE control to produce clean
treble booster action with enhanced drive and EQ or have a
combination both silicon and germanium distortion with inter stage
EQ.This unique set up gives brand new life and tone variation.
This controls the inter stage passive equalisation between
the 1st stage Silicon Drive section and the final Germanium treble
booster section. It has been carefully voiced to give a very
musical and useful tool when setting up the final desired tone.
This controls the final output level, which has more than enough
output boost capability to overdrive the 1st stage of the amplifier
being used. |
MULTI-MODE OUTPUTS / HARD WIRE BYPASS/ TWO BUFFERED OUTPUTS : The Concorde+ has a true hard wire output plus two buffered outputs that can drive long cable lengths with no high frequency loss. These buffered outputs are disconnected when the hard wire output is being used. This means that all performance situations are catered for whether you want a true hard wire output or your situation calls for the advantages of buffered outputs. BATTERY LIFE :150Hrs or more using a premium grade alkaline 9 Volt type. RAPID BATTERY CHANGE :No more screws to loose!.. Slide the front panel back and there is the battery. It could not be simpler or faster. EXTERNAL POWER ADAPTER / SUPPLY :An external AC adapter (not supplied) can be used and access is through a standard DC power jack ( 2.1mm centre pin ) situated next to the jack sockets. Internal onboard filtering ensures that optimum low noise performance is maintained and diode protection provides peace of mind in case of polarity setting mistakes. Connection protocol:It uses the standard negative centre pin connection protocol used by many leading manufacturers. Specifications:9 volt DC. Regulated output is recommended. Current rating:50mA or more. ERGONOMIC DESIGN / PEDAL BOARD FRIENDLY :The position of the jack sockets and DC power jack are all on the same side of the enclosure and face away from you thus enabling the effect to be optimally positioned in pedal board set-ups. Size:Width 170 x Depth 112 x Height 57mm. Weight : 618g with battery. |
